ipfw shaper bandwidth not dynamicly allocated...

[Martes Wigglesworth]

Greetings, all.

I am having a bit of trouble with shaping, an a multi-subnet
natd/packet-filter/traffic-shaper.

My woes:

I set the rule, just after divert, "queue 1 log all from any to
${interalnet} in recv ${outerinterface}," with the following config for
the queue/pipe:
"queue 1 config pipe 1 mask dst-ip 0xffffffff," and " pipe 1 config bw
256Kbit/s."  
The pipe limits and the dynamic queues are created per each ip on my
subnet that has traffic, however, the empty pipes remain until the
client is shutdown or taken off the network.  Also, the bandwidth is not
dynamically destributed to the hosts on the subnet(s).   Meaning, when I
am the only client, I get just under full bandwidth, however, when there
are more then three or four users, the bandwidth drops to about
18Kbit/s.  Is this normal?  If I give the pipe 256Kbit/s then we get
about 20Kbits/s not 256/8=32Kbit/s.  Am I missing something?  Also, even
though my queues don't disappear, shouldn't the only queues being
bandwidthed be those with traffic?  Why am I not seeing dynamic usage? 
I thought that the pipe would only be split while there is traffic in
each queue?

Any help is surely appreciated, and really desirable.

Respectfully.
